Among the longest rivers of Canada are 47 streams of at least 600 km (370 mi). In the case of some rivers such as the Columbia, the length listed in the table below is solely that of the main stem. In the case of others such as the Mackenzie, it is the combined lengths of the main stem and one or more upstream tributaries, as noted.
With an average flow at the mouth of about 3,475 cubic metres per second (122,700 cu ft/s), [16] the Fraser is the largest river by discharge flowing into the Pacific seaboard of Canada and the fifth largest in the country. [17] The average flow is highly seasonal; summer discharge rates can be ten times larger than the flow during the winter. [17]
Rivers with an average discharge of 5,000 m 3 /s or greater, as a fraction of the estimated global total. This article lists rivers by their average discharge measured in descending order of their water flow rate. Here, only those rivers whose discharge is more than 2,000 m 3 /s (71,000 cu ft/s) are shown. It can be thought of as a list of the ...

Its extensive watershed drains about 20 percent of Canada. [9] It is the largest river flowing into the Arctic from North America, and including its tributaries has a total length of 4,241 kilometres (2,635 mi), making it the thirteenth longest river system in the world. [10]
The river's physical characteristics include whitewater rapids, large lake systems, waterfalls, deep valleys and gorges, as well as tidal flats. [2] It is 483 kilometres (300 mi) long, has a mean discharge of 590 cubic metres per second (21,000 cu ft/s), and its drainage basin covers 108,000 square kilometres (42,000 sq mi).
The second longest river in North America and the United States is the Mississippi River (2,320 mi (3,730 km)). The Rio Conchos (350 mi (560 km)) is the longest river in Mexico. The longest river in Canada is the Mackenzie River (1,080 mi (1,740 km)). Some of the longest or otherwise notable rivers include the rivers listed in the table below.
It is the second longest river in Canada. Lake Champlain and the Ottawa , Richelieu , Saint-Maurice , Saint-François , Chaudière and Saguenay rivers drain into the St. Lawrence. The St. Lawrence River is in a seismically active zone where fault reactivation is believed to occur along late Proterozoic to early Paleozoic normal faults related ...
